Water purification

In step 1, waste water is mixed

• floc
• coagulation
• filtration
• aeration

In step 2 the water is passing through baffles to slow it down and allow particles to sink.  What was added to before this step?

• floc
• alum
• lime
• chlorine

This process allows us to drink ocean water.

• filtration
• coagulation
• desalination
• sewage

This is the mud and goop that needs to cleaned out of sewage.

• sludge
• floc
• alum
• coagulants

This is causes no recharge to the aquifer.

• sludge
• sewage
• desalination
• drought

These are tiny particles

• alum
• floc
• sludge

What is the purpose of chlorine?

• make water smell clean
• disinfect
• create floc
• make water clear

The cleaning process of putting water through several screens

• coagulation
• sedimentation
• filtration
• aeration

When a resource is used in a responsible way

• drought
• conservation
• desalination
• coagulation

Waste water and solid waste

• sludge
• sewage
• floc
